Presumably you are a citizen of the USA, all of whose paper money is the

We learn how to read our numbers in 1st grade. It is not that
confusing.

It is to blind people. Many years ago, I used to deliver groceries to
a blind couple. They had to be very careful how the bills were places
in sequence so they could use the proper denomination. I handed them
change, one type of bill at a time. I also put away some of the
canned good for them, peas here, corn there, etc. so they could tell
what they reached for.

The different sizes of the Euro bills make a lot of sense for the
vision impaired. So does using durable coins for 1 and 2 Euro, instead
of using paper that is easily damaged.
